Mean, Mode & Median?

Question

Could somone explain to me how each of these work using this as an example please:

The mean monthly rainfall over 6 months was 90 mm.

What was the total rainfall?

Answer 1

mean is another word for average

so it is saying the average rainfall over 6 months is 90 mm

so 6*90=540mm

Answer 2

Mean = arithmetic average of a set of number, i.e

= sum(a1, .. a(n))/n

Median is the middle number out of an ordered set of numbers. i.e.

Out of this set: [1, 5, 7 ,8, 11, 17, 19], 8 is the median

Mode is the most frequent number out of a set of numbers. For example, if you sample n buckets of butter, and weigh them, and found the most frequently occuring weight is 451 grams, then that is called the mode.

Answer 3

the mean is the average amount of rainfall over 6 months (90 mins)

the mode is the amount of mins that rain took place throughout the 6 month time period

the median is the least amount of rain (in mins) over the 6 month period subtracted from the most amount of rain (in mins) over the 6 month period

hope this helps :)

best answer? :)
